smtp.office365.com

Add 8.8.8.8 as one of the dns servers.

As an IT consultant, who still has a foot in the copier business.
It is getting to be best practice to disable SMTP and legacy authentication for Office 365. As part of increasing the secure score in office 365.
As part of our business processes we have been moving our customers copiers over to SMTP2go with a private domain. We've found that this is a great way to keep our customers working and secure/compliant.
